LOG-GRAB.

Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed December 17, 1908. Serial No. 468,064.

I To all whom "it may concern:

Be it known that I, HORACE M. Romans, a citizen of the United States,residing at Corry, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Log-Grabs, of which thefollowing is a specification, ref erence being had to the accompanyingdrawings.

My invention relates to improvements in log-grabs; and an object of myinvention is to provide a log-grab which will be simple in construction,comparatively cheap in manufacture and eihcient in use.

Another object of my invention is to provide a log-grab with meanswhereby the log-grab may be readily driven into the log and may bereadily withdrawn therefrom without danger of breakage.

In the drawings illustrating the principle of my invention and the bestmode now known to me of applying that principle, Figure l is a sideelevation of my new loggrab; Fig. 2 is a front elevation of the same;Fig. 3 is a section on the line A-A of Fig. 1; and Fig. 4 is aperspective view of the rear portion of the log-grab.

The shank a is that portion of the log-grab which lies outside of thelog when the driving tooth b is fully driven; and the line indicates thesurface of the log when the driving tooth b is so positioned. In thisposition of the driving tooth, the lower face 0 of the shank will lieagainst the out-side of the log as is indicated in Fig. 1. The front endof the shank is formed with the usual hole (Z for the insertion of ashackle or chain link, by which the log-grab is connected with adraft-device. Below the hole or eye (Z the end of the shank is formedwith a spur or tang e, which inclines downwardly and forwardly as shown.This inclination of the spur e tendsto make the driving of the loggrabmore easy. The shank a and the driving tooth Z2 are formed with beveledfaces f at the bend or angle where the front face 9 of the tooth joinsthe lower face a of the shank. These beveled faces f are best shown inFigs. l and 3..

The rear portion of the shank a is formed with a tailpiece h which isbulbous or eggshaped as is, perhaps, best shown in Figs. 2 and 4. Thistailpiece it extends in rear of the prolongation of the rear edge 2' ofthe driving tooth. The projecting end of the tailpiece h serves toreceive the upward thrust of the spike end of a peavey, pike le- "er orother extracting instrument adapted to be used as a lever for pullingthe driving tooth Z) out of the log. The projecting rear end of thetailpiece it lies so far above the plane of the lower face 0 of theshank that it never enters the log; so, there is always left between theouter surface of the log (indicated by the line w-w) and this end of thetailpiece an interval y. This allows the Woodsman to insert the spikeend of the peavey more readily underneath the end of the tailpiece h.Again, care has been taken in designingthe rear end of the shank tofacilitate the movement of the spike of the peavey to its positionbeneath the end of the tailpiece, as will be seen from an inspection ofthe drawings. Thus, the tailpiece h being rounded and bulbous andinclining downwardly toward the rear end of the shank, when the Woodsmanforces the end of the peavey against the rear portion of the shank, theend of the peavey will be guided to the angle or groove where thetailpiece h meets the lateral face of the shank and will thence beguided by the downward inclination of the tailpiece to its workingposition underneath the rear end of the latter. Further, by reason ofthe rounded shape of the tailpiece, the metal of the latter will not begouged out by being struck with the spike end of the peavey; and even ifthe woodsmans aim is poor, the spike end will not be dulled, thelog-grab itself will not be weakened by the misdirected blow and the extracting tool will be positioned quickly and accurately under the rearend of the tailpiece despite the poor aim of the Woodsman. The roundedegg-shaped tailpiece h overhangs at its rear the lateral faces of theshank a and any blow delivered against the tailpiece will be transformedinto a glancing blow, the spike end of the peavey being directed belowthe tailpiece at its projecting rear end. In a similar way, if it bedesired to place the spike end of the peavey beneath the body portion ofthe shank near its junc tion with the tooth and in front thereof, thebeveled faces f will serve to save the metal of the log-grab, to preventthe 'dulling of the spike end of the peavey and to guide the latterquickly into place.
